The Sisterhood of Salaam Shalom was begun in Los Angeles six years ago by Muslim and Jewish women to share their experiences as members of religious minorities in the U.S. Today there are chapters in more than 50 cities, part of a growing desire among Americans of both faiths to stand together. When California mosques received a threatening letter calling Muslims a "vile and filthy people" and saying that Donald Trump "is going to do to you Muslims what Hitler did to the jews [sic]," Jewish groups were among the first to reach out, said Ojaala Ahmad of the Council on Islamic Relations in Los Angeles. "More people have become aware of their common faiths given the rise of toxic anti-Muslim, anti-Semitic hate," said Haroon Moghul of the Center for Global Policy think tank.
